Seminar - 'eXtended Hybridizable Discontinuous Galerkin (X-HDG)', by Sònia Fernández
Wednesday, March 29th, 2017. Time: 12h
Place: O.C. Zienkiewicz Conference Room, C1 Building, UPC Campus Nord, Barcelona.
The eXtended Hybridizable Discontinuous Galerkin method (X-HDG) is an efficient HDG method , incorporating the eXtended Finite Element (X-FEM) philosophy for the solution of problems with material interfaces or voids. X-HDG was first proposed for heat problems with voids in  and has been further developed in for the solution of bimaterial heat and flow problems. X-HDG inherits the advantages of X-FEM methods  (a level-set representation of the interface is considered, and the computational mesh is not required to fit the interface, simplifying and reducing the cost of mesh generation and, in particular, avoiding continuous remeshing for evolving interfaces or boundaries), while keeping the computational efficiency, stability, accuracy, optimal convergence and superconvergence of HDG.
